deadline is now deprecated, but should be taking its value from the configuration if set (#822)

* test that demostrates that deadline is not working if comes from the config

* overriding timeout with deadline when only deadline is different from its default value

* tests were not passing. default value for Deadline, that now only comes from config, is 0. Plus static check is going to fail because of deprecated cfg used

* golangci should use the latest golangci-lint version, that is the one deprecating deadline in favour of timeout

* README updated - looks the ci config in this project is used to generate usage instructions.. great!
